1976 Standard Atmosphere Calculator

The 1976 standard atmosphere calculator computes atmospheric properties like density, temperature, pressure and speed of sound up to 86 kilometers geopotential altitude. This tool is mainly used by aeronautical engineers to perform calculations for aircraft. But if you always wanted to know the average air temperature at 30,000 feet. Go ahead and give it a try.


To calculate atmospheric properties:

  • Click the Calculator button in the Menu.
  • Set the altitude and select the desired input and output unit types.

Table Wizard

Online Standard Atmosphere tables can be generated using the Table Wizard. You can select the atmospheric properties and the unit types to be shown.


Click the Graphs button in the Menu to view graphs of the 1976 Standard Atmosphere properties as function of the altitude.


Click the Options button in the Menu to set calculation options, such as number of digits after decimal point. All options will be remembered for future sessions.
